In order to ensure that there is no water inrush accident in the recovery of No. 2 coal seam in Zhongxing Coal Mining Group of Minxi Mining Group, an evaluation model for the risk of water inrush from the floor was established, combined with the hydrology and geological conditions of No. 2 coal seam, water inrush from the coal floor. The risk of water inrush from coal seam floor was divided, and the vulnerability index method was used to predict the risk of water inrush from the floor. The risk of water inrush from the floor was divided into 5 sections: dangerous area, moderate dangerous area, transitional area, safe area. The two evaluation models complemented each other and combined the evaluation results of the two models. It was concluded that there was a risk of water inrush when the coal seam has developed geological structures, the water pressure in the aquifer was strong, and the thickness of the effective aquifer was thin. It was necessary to strengthen the water exploration and release operations.
